Abstract

The invention relates to an auger supporting device applied to the oil field industry. The auger supporting device comprises a concave spherical surface supporting plate, a convex spherical surface pin shaft, an auger shell, an upper guiding sleeve, a lower guiding sleeve, a supporting frame, a base plate, a moveable rectangular pipe, a fixed rectangular pipe, an oil cup, a locking nut, a central spindle, a nylon roller, a U-shaped bracket and a kidney-shaped hole, wherein the convex spherical surface pin shaft is welded on the auger shell; the concave spherical surface supporting plate is welded on the moveable rectangular pipe; the convex spherical surface pin shaft is inserted into a pin hole of the concave spherical surface supporting plate; the moveable rectangular pipe is sleeved in the fixed rectangular pipe; the upper guiding sleeve and the lower guiding sleeve are combined with each other through a bolt; the lower guiding sleeve is welded on the supporting frame; the base plate is cushioned under the supporting frame; the convex spherical surface pin shaft is matched with the concave spherical surface supporting plate; the oil cup is mounted on the concave spherical surface supporting plate; the U-shaped bracket is welded on the supporting frame. A spherical surface pair of the device is rotated around the centre of sphere and a certain infinitesimal displacement is supplied, so that the error caused by processing or assembling is compensated. The spherical surface pair is rotated and the infinitesimal displacement is supplied, so that the additional force at the pin shaft is avoided and the service life of the sand-conveying auger is prolonged.

Description

technical field [0001] The invention relates to an auger support device for a sand mixing vehicle in the oil field industry. Background technique [0002] The sand mixing vehicle is an important supporting equipment in the oil field, which is responsible for providing fracturing fluid to the fracturing vehicle. There is a sand conveying auger at the tail of the sand mixing vehicle, which is responsible for providing proppant to the sand mixing vehicle. The auger and the ground have an inclination angle of 45 degrees. During on-site operation, it is necessary to drop the sand auger to the ground, and the two sand augers should be separated to facilitate on-site operation. The current support structure of the sand conveying auger has high processing requirements. Even if the processing requirements can be met, the assembly requirements are also very high. The workload and difficulty of on-site assembly are very large, which affects production efficiency; , bringing additiona...
